Well, Due doesn't use an FTDI chip, so that won't help any. The driver for the 16u2 chip used instead SHOULD be built into the Mac. (it would show as /dev/usbmodem* instead of /dev/usbserial*, but that shouldn't fool the Arduino menu.) When you say "programming port", you mean the one closest to the power jack, right?

@westfwOkay thanks for clearing that up about the FTDI drivers. I was looking for /dev/*usbmodem* but unfortunately I couldn't find anything. And I think I have the right port (It says programming underneath it?). I thought the one next to the reset button was native USB.

@James C4SWhile I'm not 100% sure what I'm looking for, I don't find anything that resembles Arduino and no additional entries show up after plugging in the Arduino.

The fact that 'nothing happens' on the computer side when i plug in the Arduino led me to believe the issue might be the cable, as I got this cable separately from the Arduino. But how likely could the cable 'not work' but still provide electricity to the Arduino?If it's not the cable however I really don't know what the issue could be.

@James C4SI did hit cmd-r. And interesting! I always thought those cables were uniformly designed - but if micro b usb cable ? micro b usb cable that is probably the issue. Thanks for your reply and I will try to obtain a new cable before trying anything else.

I received my Due today and it too isn't showing up in the serial port menu. Whether it is plugged in to the native usb port or the programming usb port, it doesn't appear. I checked System Information and it doesn't get listed in the device tree. Running ioreg in terminal didn't show the device either.

I thought it might have been not enough power over the usb cable so I plugged in 5v in the DC jack and still no luck.

Is there a way to reset the Due?

Any help is greatly appreciated.

EDIT:I should add that the L led is solid along with the On led, if that means anything.

EDIT 2:I downloaded the IOUSBFamily Log Release from developer.apple.com to see if the OS X usb subsystem could shed any light on the situation. The only console message that _might_ be related is this.

1/26/13 7:04:58.758 PM MDCrashReportd[326]: 326:2042986880|MDCrashReportd.m:deviceAttached| ERROR: Could not get a USBMux endpoint for the device with uid b7010c79b5bb8aa7f15161ad8d5af162f5ac38af. Ignoring.

It is had to ascertain whether this message is related to the Arduino Due at all as it does show any usb id's in the message.

It looks like the Due is bricked. Can anyone tell me if there is a way to unbrick it?
